Why is DIN 2304 important?

Too often, the adhesive industry faces the challenge that the quality of adhesive bonds is difficult to verify since testing often involves damaging or destroying them. Therefore, an alternative approach is needed. DIN 2304 establishes clear rules and quality standards that structure application and control processes. This enables quality assurance without having to subsequently test adhesive bonds.

While not itself a law, DIN 2304 and users’ adherence to it can help demonstrate responsible conduct, which is crucial in the event of an incident. In a legal dispute, this standard offers a means to determine liability regarding the quality of a component or adhesive bond, and courts are likely to refer to DIN 2304 in such cases. If a user fails to comply with the standard, they may face scrutiny for not aligning with current technological standards. Conversely, companies adhering to the standard can relieve themselves of guilt through documentation and evidence. Despite being legally non-binding, the standard is extremely relevant in practice. 

How does the standard structure adhesive processes?

DIN 2304 organizes adhesive processes in companies through four core aspects:

1. Adequately trained adhesive personnel: Having trained professionals is crucial for companies to properly adhere to this standard. Their expertise will be central to the design, planning, manufacturing, and maintenance of adhesive technology.
2. Suitable work and manufacturing environments: Maintaining an ideal work environment is necessary for performing adhesive applications precisely and professionally. This new standard focuses on technical regulations as well as safety and environmental protection.
3. Classification of adhesive applications:  Dividing adhesive applications into safety classes, from S1 (high) to S4 (none), ensures they meet specific application requirements. Quality assurance is the responsibility of the designer or construction manager, who assesses adhesive bonds based on potential impacts.
4. Lifecycle requirements: It must be proven that the adhesive bond meets the requirements and sustains expected loads over its lifetime. Here, the designer and component manager share responsibility.
